HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 592,601, dated October 26, 1897- Application filed July l5, 1895. Renewed March 25, 1897. Serial No. 629,268. (No model.)

To @ZZ whom. it' may concern:

Be it known that I, JOHN L. ARNOLD, of Toledo, county of Lucas, and 4State of Ohio, have invented certain new and useful Improvements in I-Iydrocarbon-Burners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this speciiication.

My invention relates to a hydrocarbonburner, and has for its object to simplify the construction and construct a burner complete as an article of manufacture either of the character adapted for cook-stoves, heaters,-

or furnaces.

A further object is to form the body of the burner with an internal vaporizing-conduit in which the oil shall be gradually and progressively vaporized by means of the heat generated by combustion within a chamber inclosed by the vaporiZing-conduit. l

A further obj ect is to form an air-mixer integral with the body portion and coincident with the combustion-chamber, whereby the proper amount of air is induced by force of the jet of vapor and intimately mixed therewith prior to combustion.

Vith these objects in view the invention consists in the parts and combination of parts hereinafter described, and pointed out in the claim.

In the drawings, Figure 1 is an elevation of a complete burner. vaporizer-chamber. Fig. 3 is a transverse section on lines fc Fig. 2. Fig. 4 is a like view on lines y y, Fig. 2.

l designates a pan of greater length than the vaporizing-chamber 2, whereby the front end 3 projects beyond the forward end of chamber 2 a sufficient distance to receive a sufficient supply of oil necessary to start the initial fire and heat the generator to a degree to vaporize the oil contained therein.

Pan lis formed with supports 4, having V- shaped recesses to receive the V-shaped lower portion of the generator and hold the same rmly in place. The vaporizer is formed with Fig. 2 is a plan of the an integral conduit 5, extending from the forward end along one side, from thence across the rear end, and communicating with a like conduit 6, formed-in the opposite side, whereby the oil when introduced through pipe 7, screwed into the end of conduit', is caused to travel the entire length of the conduit and iind an exit in a vaporat the exit of conduit 6, into which is screwed a pipe 8, upon which 6o is screwed an L 9, into which is screwed a nipple 10, havinga cap l1 upon the outer end.

Vithin the center of the vaporizer is formed an open-top chamber 12, the sides defining the same being the inner wall of the conduits 5 and 6, and the bottom wall thereof being the web 5', which connects the two conduits at their lower edges. This chamber extends from the inner wall 13 of the transverse conduit at the rear end of the vaporizer to and 7o through the front wall14 of the same. A portion, however, of the chamber Vis inclosed by awall 15, thereby forming a circular inlet for the gaseous Vapor through which it is discharged into the chamber 12 througha jet-ori- 75 ice 16 in the nipple 10. This circular inlet subserves the purpose of an air-mixer, as the force of the vapor as it passes through the circular inlet induces a volume of atmospheric ailgwhich commingles With the gaseous 8o vapor in quantity to support combustion and is heated to a high degree within the vaporizing-chamber prior to combustion.

17 designates a top plate formed with serrations 18 upon the lower face, which, when 85 resting upon the uppersurface of the vaporizer, forms exits for the gaseous vapor fromthe vaporizing-chamber, and as the gaseous vapor, now properlydiluted with atmospheric air, issues therefrom it is ignited and burns 9o in a plurality of jets in imitation of the usual combustion of natural gas.

Top plate 17 is preferably formed with a longitudinal rib 19 to prevent warping by heat. f

In operation a small quantity of oil is allowed to run through the jet-orifice 16 into pan 1 and is ignited. The flame resulting from the combustion of the oil within the pan envelops the lower sides of the vapo- 10o and progressively Vaporizing the same, initially heating the oil at the ingress of conduit 5, and increasing in temperature in its course until fully vaporized at the exit of conduit 6, when it is discharged through jetorifice 16 into the mixer, commingling with the induced air, and finally discharged into chamber l2, which being intensely heated superheats the gaseous Vapor and air, when the gaseous fuel finds exit through the opening 18, at which point combustion takes place.

It Will-be seen that the burner can be made as an article of manufacture to be shipped to any point and adapted to any form of combustion-chamber, as the burner. may be of the shape shown or of any shape to conform to a heating stove or furnace.

The Value of the novel construction of the Vaporizer will be apparent, as by the continuous conduits 5 and 6,cast integral with the body of the vaporizer, all couplings and connections incident to the construction of Vaporizers is avoided, thereby obviating the usual leakage incident to joints at this point of great expansion and consequent pressure. I also consider the feature of the dilution of the hydrocarbon Vapor by an induced *curinlet-pipe for oil entering one conduit, and anexit-pipe for gas connecting with the opposite conduit and extending downward in line with the center of the mixing-chamber, and an inlet into the mixing-chamber comprising an integral casting to connecting-web leading to substantially midway of the mixingchamber, substantially as described.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses.

JOI-IN L. ARNOLD.
